Determine the factors for 17 up to 17 since that is the minimum of the 2 numbers1,17

Determine the factors for 68 up to 17 since that is the minimum of the 2 numbers1,2,4,17

The common factors between them are 1,17The greatest common factor between them is 17Since the Greatest Common Factor of both numbers ≠ 1, the numbers are not relatively prime (co-prime)Since the Greatest Common Factor of Both Numbers is both ≠ 1 and have a difference of two, the numbers are not twin prime
